GENERAL LIMEWASH APPLICATION
INSTRUCTIONS & TECHNIQUES
(For detailed diluons and instrucons for specic type of surfaces including new
and painted drywall/wood, please see APPLICATION CYCLES ON DIFFERENT
TYPES OF SURFACES).
Stone & Brick LIMEWashES
BRUSH APPLICATIONS
When applied to natural mineral surfaces such as stone, brick, or NHL 3.5 cements
Classico Limewash can be applied as an anque wash o (limewash), rst dilung
the product with water then applying on a per-dampened surface with a large
masonry brush used for lime paint.
Technique requires sucient pre-weng with water of the masonry surface for
un-painted brick or stone to permit a slow set with the limewash applicaon.
Classico Limewash must be diluted with water between 100 – 150% to permit
sucient lime paint material to remain.
Tesng must be determined by several aempts at dierent diluons of lime
paint with water, as well as surface heat condions, water pressure, and type of
spray p (wide or narrow), to remove the correct amount of lime paint to create an
accurate historical eect. Then, you can begin washing with an adjustable spray
hose with at least 55+ PSI pressure, remove the amount of desired paint material
without over or under washing. Occasionally, 2 – 3 types of diluon are required
to create the desired eect, requiring several coats, with sucient drying me in
between. Correct applicaon and removal will provide a historical washed paint
eect for new or exisng construcon.
1ST COAT: Dilute Classico Limewash with 100% water, 15 liters of water per one
(1) 15-liter bucket to 150% diluon, 22.5 liters of water per one (1) 15-liter bucket.
For 1 liter sizes: Classico Limewash diluted with 100%, 1 liter of water per one (1)
liter product, Classico Limewash diluted with 150%, 1.5 liters of water per one (1)
liter product.
Diluons with water are suggested as general guidelines for applicaon, but
paint applicator may adjust diluons as needed to meet best uses for ease of
applicaon, job site requirements and nishes.
PRE-WETTING: For brick or stone it is required to pre-wet all masonry surfaces
with water thoroughly to facilitate slow drying of the limewash. This also assists
limewash paints to absorb deeper into the masonry surface. Do not apply paint
to overly wet/dripping surfaces. Brick walls should be weed down with water
several mes.
APPLYING WITH A BRUSH: Apply the pre-diluted Classico Limewash with a large
masonry brush, starng applicaon at the top of the pre-dampened wall, working
with the brush le to right, right to le (for brick courses), and for stone apply in
a criss-cross paern. Back brush as necessary to remove runs from the vercal
mortar joins, and connue this applicaon as rapidly as possible, moving down the
wall to the ground level. Time allowance for a whole wall coverage with limewash
is generally 30 - 40 minutes. Try to work in whole wall secons, corner to corner,
top to boom. It is recommended to not paint masonry surfaces exposed to full
midday, direct sun exposure. Depending on heat and direct sun, me may be
reduced to 10 - 15 minutes.
USING THE SPAY HOSE: Once the limewash begins to pull or dry, usually
indicated with 50% of each brick or stone, half white (indicates dry), and the other
half wet (darker/wet), it is the ideal me to begin using an adjustable hose spray
(handle type with a plasc p adjustment), to wash o the lime paint in short
bursts, narrowing or broadening the spray p as required to remove the quanty
of limewash desired, and controlling the force of the spray by the pressure handle.
GENERAL METHODS FOR ACQUIRING ANTIQUE EFFECTS: Typical anque
methods are based on observaons of me-worn lime painted surfaces. Meaning
that environmental erosion by sun, wind, rain, occurs more rapidly on brick or
stone areas not protected by eve overhangs and roofs, and typically the upper half
secons of the walls will be less worn than the boom half secons of the wall
toward the ground (where runo from the wall above and back splashing from the
ground cause deterioraon to occur more rapidly). It is important that the overall
anque look of the limewash is gradual and appears natural. Observe your results
oen from afar, so that you can see the eect of the limewash from a distance.
2ND COAT: 2nd coats are required only when necessary, where perhaps too
much lime paint was removed in one area and a touch up is required. Always re-
wet the dried surface areas with water, then applying the limewash starng at the
center of the area and move out to the sides, overlapping with as lile limewash as
necessary where you do not need to touch up. It is suggested to use a 2nd clean
brush with only water to feather out the overlap so that as the limewash dries, the
touch up will not be visible. Allow the touch up to dry as indicated above and rinse
o with the spray p to re-create the nish technique you have adapted.
Touch ups may require greater diluon of Classico Limewash than when used
for the 1st coat. If the standard diluon you used was 100% with water, a small
quanty of Classico Limewash should be diluted with water at 150%, or 1.5 lts of
water to one (1) liter of product.
3RD COAT: 3rd coat applicaons usually serve to create more dynamic
dimensional nishes, such as applying a 150 - 200% diluon with water and
re-coang areas under roofs, roof eves, under brick row locks, ledges, or in higher
upper wall secons to help create depth. It is suggested to only cover narrow
areas, applying as needed to create a slightly thicker look than the main wall areas.
Follow the touch up instrucons indicated in the 2nd Coat above.
Applicaons should not be performed in air temperature lower than 13°C / 55°F
and not above 32° C / 90°F.

FULL COVERAGE stone & brick
BRUSH APPLICATIONS
PRIMER: For interior or exterior applicaons where the surface base to be
painted is a non-mineral surface (i.e., acrylic paint, drywall, portland cement
stucco, wood), apply 1 coat of BioGrip Micro or Medium, applying generously, and
allow to dry for 8 – 12 hours prior to applicaon of 1st coat Classico Limewash.
1ST COAT: Dilute Classico Limewash with 50% water, 7.5 liters of water per one
(1) 15-liter bucket to 120% diluon, 18 liters of water per one (1) 15-liter bucket.
For brick or stone it is required to pre-wet all masonry surfaces with water
thoroughly to facilitate slow drying of the limewash. This also assists limewash
paints to absorb deeper into the masonry surface. Do not apply paint to overly
wet surfaces. Allow 1st coat to dry for at least 2 – 8 hours before applying 2nd
coat. Brush, roll or spray the rst coat. Using a large brush and painng by hand
will create the best results. Classico Limewash can be applied to non-acrylic
painted natural mineral surfaces such as stone, brick, NHL stucco lime plasters,
without the use of a primer.
2ND COAT: Apply Classico Limewash diluted with 50% water, 7.5 liters of water
per one (1) 15-liter bucket to 120% diluon, 18 liters of water per one (1) 15-liter
bucket. Classico Limewash should be applied wet on wet. This means that the
brick or stone surface should be dampened throughly with water before the
applicaon of the 1st Coat, and the same with the 2nd Coat when applying onto
the 1st Coat of Classico Limewash. Keep painted limewash walls damp when
applying the 2nd Coat. Use an adjustable spray hose aachment to dampen walls.
Apply with brush when possible. Painng with a brush in a crisscross paern will
create a very slight natural chromac nish. Allow 2nd coat to dry for at least
1 – 4 hours before applying a 3rd coat.
3RD COAT: For wash or glaze aects Classico Limewash can be diluted from 150
– 200% with water. Extreme diluons for the exterior should be applied on 1st
or 2nd base coats only. Always paint wet on wet. It is suggested to nt your lime
paint darker or lighter for glaze eects.
Diluons with water are suggested as general guidelines for applicaon, but
paint applicator may adjust diluons as needed to meet best uses for ease of
applicaon, job site requirements and nishes.

FULL COVERAGE
1ST COAT: Classico Limewash is a non-aggregate paint and can be used in most
airless sprayers. Dilute Classico Limewash with 50% water, 7.5 liters of water
per one (1) 15-liter bucket to 120% diluon, 18 liters of water per one (1) 15-liter
bucket when applying paint to achieve a full coverage nish. For brick or stone it is
required to pre-wet all masonry surfaces with water thoroughly to facilitate slow
drying of the limewash. This also assists limewash paints to absorb deeper into
the masonry surface. It is suggested to dampen previously all masonry surfaces
with water thoroughly, so as to assist lime wash paints to absorb deeper into the
masonry surface. Do not apply paint to overly wet surfaces. Allow 1st coat to dry
for at least 2 – 8 hours before applying 2nd coat. Parcular care must be taken
when using a sprayer on brick or stucco to apply product abundantly, without
causing paint runs, so as to permit proper millage thickness for longer durability.
2ND COAT: Classico Limewash paint should be applied wet on wet. This means
that the brick or stone surface should be dampened throughly with water before
the applicaon of the 1st Coat, and the same with the 2nd Coat when applying
onto the 1st Coat of Classico Limewash. Keep painted limewash walls damp when
applying the 2nd Coat. Use an adjustable spray hose aachment to dampen walls.
Dilute Classico Limewash with 50 – 120% water, and apply as instructed above for
1st coat.
Diluons with water are suggested as general guidelines for applicaon, but
paint applicator may adjust diluons as needed to meet best uses for ease of
applicaon, job site requirements and nishes.
SPRAY TIP USAGE: Classico Limewash may be applied using an airless sprayer.
Apply paint product with a # 0.019 – 0.021 mm size spray p. Always use new
spray ps for starng a paint job for best results. This will also conserve the
amount of paint necessary to complete the job.
GRAIN SIZE: 0.01 mm
MIXING PAINT & WATER
ROMABIO BioCalce lime paint formulas are concentrated and require water to be
added to them for proper use. This process means we can sell more coverage in
an economical package that decreases the cost for transport, reduces the carbon
footprint, and is less impact to the environment.
Mix paint and water with an electric drill and paint paddle, or mix well by hand! If
water is sing on the top of your mixture, the paint is not properly mixed!
TOOLS
Apply with an appropriate masonry brush composed of synthec bristles or with
an appropriate sprayer and sprayer p. Paint rollers cannot be used to apply
BioCalce lime paints.
TOOL CLEANING
Brushes, sprayers, rags, or sponges should be cleaned immediately aer use with
water and a mild detergent or dish soap.
DRYING TIME
For Wash O Eects, the Limewash applicaon is generally a 1 coat process,
but a 2nd or 3rd coat may be applied for decorave eects. Allow newly applied
limewash to set 10-40 minutes depending on temperature and sun. Wash o
process can begin when bricks appear half wet/half dry, before painted surface is
completely dry to the touch.
For Full Coverage Applicaons, allow a drying me between coats of at least
2 – 8 hours for the 1st coat, and with successive coats allow at least 1 – 4 hours
between coats. With lower temperature and humidity more me may be needed.
Do not apply Classico Limewash on the exterior if there is a risk of severe
thunderstorms or showers during the 12-hour drying me needed for product to
dry and carbonize correctly.

hundreds of years, and are typical of the historical nishes frequently observed
since Medieval and Renaissance periods.
Classico Limewash applied at higher diluons of 100%+ can be easily steelwooled
or scotchbrited to remove excess material to allow the underneath coat to stand
out more predominantly or to ll in the open grains of hardwoods. Applying these
diluons types onto wood will allow for a multude of eects and also permits
the following applicaon of varied layers of paint products, manipulated to create
beauful eects, i.e. such as EcoCalce Semi-Transparent & Glaze, TerraMare
Velatura and most can be sealed with LowCer Varnish or LowCera SoWax.
Classico Limewash upon drying aer applicaon onto a wood surface can be
wiped with a rag or sponge, and/or lightly sanded, steelwooled, or scotchbrited.
Eects can be varied and require tesng before a nal decorave nish is
acquired.
EXTERIOR: Applicaon of Classico Limewash on wood should not be used on
exterior surfaces that are exposed to rain or water, unless they are properly
sealed with TerraMare Velatura, and coated with LowCer Exterior Varnish, as this
may result in the removal of the lime wash or cause the tannins or resins in many
woods to discolor the pana.
1ST COAT: Dilute Classico Limewash with 100% water, 15 liters of water per one
(1) 15-liter bucket to 150% diluon, 22.5 liters of water per one (1) 15-liter bucket.
For 1 liter sizes: Classico Limewash diluted with 100%, 1 liter of water per one (1)

Wet wood surface with water, using a brush, sponge or hand sprayer to expand
wood grain surfaces. Dry damp wood surfaces, then apply diluted limewash onto
the unpainted wood surface. Allow painted surface to fully dry, then remove
excess limewash from the wood surface using steelwool or Scotchbrite type
exible abrasive pads.
Upon removal, vacuum excess dust or wipe of with a slightly damp sponge of
cloth. Classico Limewash can be applied several mes and with dierent nt colors
to create depth and dynamic decorave nishes.
SEALERS/VARNISHES: For consolidaon of limewash on wood refer to
instrucons provided in TerraMare Velatura TDS. For sealing with mae or san
varnish please refer to LowCer Varnish TDS. Other references for limewash/
ceruse nishes please refer to LowCer Stain TDS.
WARNING IRRITANT! Always use a high quality professional dust mask with
interchangeable lters when removing or sanding Classico Limewash. Inhaling
lime dust is an irritant and exposure to adults or children can provocate allergic
reacons and damages to bronchial passages or lungs.
CEMENTITIOUS board
It is not advised to use Classico Limewash for applicaon on cemenous boards.
Concrete Floors, Sidewalks Or Driveway
Classico Limewash cannot be used on portland cement based oors, sidewalk or
driveways.
REINFORCED CONCRETE SURFACES
It is not advised to use Classico Limewash for applicaon on reinforced concrete
surfaces. If required follow instrucons as indicated for ADOBE BRICK below.
CMU/concrete block
INTERIOR/EXTERIOR: Mortar joints should not be painted for about 28 days to
ensure proper curing and drying. Follow instrucons as indicated above for new
cement stuccos.
PRE-PRIMER COAT: For best results apply Potassium Silicate Concentrate, diluted
100% with water, o (1:1), or 10 liters of water per one (1) 10 liter bucket as a
pre-primer, on all new cement surfaces, applying 2 – 3 coats in rapid succession,
wet on wet, unl substrate has arrived at full absorpon, and allow to dry for at
least 2 - 3 days; or as an alternave apply one (1) coat EcoForte Consolidator with
brush, roller or sprayer diluted 100% with water, or 10 liters of water per one (1)
10 liter bucket as a pre-primer, and allow to dry for at least 8 – 12 hours.
Brick
Always wet exterior masonry walls abundantly with water making sure that virgin
masonry base has absorbed sucient water so that lime paint is not applied on a
totally dry base. Dilute Classico Limewash with 100% water, maximum 15 liters
of water per one (1) 15-liter bucket of Classico Limewash, when applying paint to
achieve a full coverage nish. Apply a 2nd coat of Classico Limewash, diluted 50 –
100% with water, depending on the density of lime paint desired for the surface.
Always pre-wet 1st coat surface with water abundantly before applying Classico
Limewash on a damp surface to enhance absorpon and durability, as well to ease
applicaon of lime paint. For wash or glaze eects see direcons as indicated in
stone and brick washes.
Classico Limewash cannot be applied to most large at areas, such as exterior
brick oors, without the risk of product deterioraon due to freeze-thaw
condions. Brick walls not covered by a roof may create poor condions for
Classico Limewash to remain integrated with brick because of freeze thaw
condions that can cause brick to deteriorate rapidly on the surface, pulverizing
as a result, thus causing lime paint to deteriorate. This situaon can occur on
chimneys, thresholds, and brick areas in contact with earth, parcularly on
the north face, where freezing condions intensify on wet brick, causing brick
to deteriorate rapidly. Brick in constant contact with damp soil may absorb
salt nitrates from the earth and this too will cause brick to deteriorate rapidly.
Applicaon by a large masonry brush is recommended.
ABSORBENT BRICK/ INTERIOR / EXTERIOR: For absorbent, unpainted,
integral brick, pre-primers or primers are not required in the applicaon of
Classico Limewash. Apply Classico Limewash directly to brick facade following
instrucons as indicated in GENERAL APPLICATION INSTRUCTIONS.
For limewash eects on interior brick, applicator is obligated to use hand sprayers,
sponges and or rags to create similar results as indicated for exterior limewash
nishes.
PRE-PRIMER COATS: None
PRIMER COAT: None
1ST & 2ND COATS: Apply one (2) - two (2) coats of Classico Limewash according
to GENERAL APPLICATION INSTRUCTIONS.
Tesng for Absorpon:
Spray brick surface with water for a couple of minutes
to determine if water absorbs rapidly into brick. Brick surfaces will appear to
be dry if the brick is absorbent. If aer spraying water onto the brick and the
brick remains wet, or has not rapidly absorbed water into the surface, then this
indicates that BioGrip Micro will be required as a primer before proceeding with
EcoDomus Mae.
NON ABSORBENT OR EXTRUDED BRICK / INTERIOR / EXTERIOR: For brick
that is nonabsorbent, such as red common brick, glazed brick, or any smooth brick
that has a slight sheen, and has been pressure extruded or red at extremely high
temperatures, will not absorb water as a general rule. Tesng can be performed by
weng a brick area with a water hose to determine if water absorbs immediately
within 1 – 2 minutes, leaving no trace of water sing on the surface. Posive
absorpon indicates no need to apply a BioGrip Micro or Medium primer. If water
sits on the surface aer weng and water has not absorbed, then BioGrip Micro
should be used as a primer in such cases.
PRIMER COAT: Apply one (1) coat of BioGrip Micro or Medium as a primer, nted
if necessary* with brush, roller or approved sprayer for ne aggregate, diluted
30% with water, or 4.5 liters per one (1) 15 liter bucket and allow to dry for at least
8 – 12 hours.
1ST & 2ND COATS: Apply one (1) – two (2) coats of Classico Limewash according
to GENERAL APPLICATION INSTRUCTIONS.
UNPAINTED WOOD
Classico Limewash can be used as a historical and decorave nish on new or
reclaimed wooden beams, wood trim, wood ceilings and even wood oors.
INTERIOR: Classico Limewash can be used for hundreds of decorave nishes
both for interior walls as well as unpainted wood surfaces. Decorave eects are
generally achieved by various degrees of diluon with water, applying onto other
Domus Mineral Paints & Primers, or directly onto wood surfaces with or without
the use of BioGrip Primers. These types of decorave nishes have been in use for

use BioCalce Flat Lime paint.
ADOBE BRICK
INTERIOR / EXTERIOR: Adobe brick being made of a composite of dirt/sand
and inorganic material is extremely suscepble to damages caused by water on
exterior surfaces. Potassium silicate paints are ideal because they will carbonize
to mineral content in the clay brick, creang consolidaon, strengthening the
external surfaces and allow them to be water resistant and permeable when
painted with BioDomus I.
PRE-PRIMER COAT: For best results apply Potassium Silicate Concentrate, diluted
100% with water, o (1:1), or 10 liters of water per one (1) 10 liter bucket as a pre-
primer, on all new, unpainted surfaces, applying 2 – 3 coats in rapid succession,
wet on wet, unl substrate has arrived at full absorpon, and allow to dry for at
least 2 -3 days.
PRIMER COAT: Apply at least one (1) to two (2) coats of BioGrip Micro or Medium
primer as indicated in GENERAL APPLICATION INSTRUCTIONS.
1ST & 2ND COATS: Apply two (2) coats of Classico Limewash according to

AUTOCLAVED AERATED CONCRETE
INTERIOR / EXTERIOR: Autoclaved aerated concrete cannot be painted,
plastered or stuccoed directly onto non-consolidated and unprimed surfaces.
Using ROMABIO Specialty Products and Primers applied onto autoclaved aerated
concrete will permit the proper applicaon of any type of paint, plaster or stucco
to be applied the surface.

Concentrate diluted 100% with water, or 10 liters per one (1) 10 liter bucket,
applying wet on wet, applying 2 – 3 coats in rapid succession unl aerated
concrete has completely and evenly absorbed the Potassium Silicate Concentrate
into surface. This process will double the strength and durability of the surfaces
of aerated concrete, as well as increase adhesion of any type of applied material.
Apply Potassium Silicate Concentrate with a brush, roller, or sprayer and allow to
dry for 2 – 3 days.
PRIMER COATS: Apply at least two (2) coats of BioGrip Micro primer as indicated
in GENERAL APPLICATION INSTRUCTIONS.
1ST & 2ND COATS: Apply two (2) coats of Classico Limewash according to
GENERAL APPLICATION INSTRUCTIONS. For FULL COVERAGE it is advised to

Decaying or Crumbling Stuccos or Powdery
Surfaces
INTERIOR / EXTERIOR: Chalking surfaces, which could prevent the proper
anchoring of the base coang must have damaged and chalky porons be removed
by pressure washing and scraping. If pressure washing is not an opon for interior
surfaces, scrub aected areas with a s brush and white vinegar or muriac acid
(1 part muriac acid and 6 – 7 parts water), and aer 3 -5 minutes rinse several
mes with a large sponge and clean water.
PRE-PRIMER COAT: For unpainted stuccos apply Potassium Silicate Concentrate
diluted 100% with water (1:1) on all damaged surfaces, or 10 liters of water
to one (1) 10 liter bucket, applying wet on wet, applying 2 – 3 coats in rapid
succession, unl substrate has arrived at full absorpon, and allow to dry for at
least 2 – 3 days. For old, acrylic-free painted stuccos, apply one (1) coat EcoForte
Consolidator diluted 100%, or 10 liters of water to one (1) 10 liter bucket, and
allow to dry for at least 8 – 12 hours.
PRIMER COAT: Apply one (1) coat of BioGrip Micro, as a primer nted if required*,

For severe cases of deterioraon, take into consideraon the removal and
replacement of damaged stucco in its enrety. Cement stuccos exisng prior to
1940 are probably made of NHL 3.5 or 5.0 (Natural Hydrated Lime Cement) and
careful inspecon and aenon needs to be taken to ensure proper replacement
and repairs. At all costs, avoid using portland based cements for restoraon or
repairs on NHL cements.
1ST & 2ND COATS: Apply two (2) coats of Classico Limewash according to
GENERAL APPLICATION INSTRUCTIONS. For FULL COVERAGE it is advised to
use BioCalce Flat Lime paint.
Coatings with Efflorescence
INTERIOR / EXTERIOR: Cement surfaces showing eorescence should be
aggressively cleaned with a high pressure washer or s brush, and then the
eorescence should be treated using a diluted muriac acid, 1 part muriac acid
and 6 – 7 parts water, and allow to react for 3 – 5 minutes. Thoroughly rinse
treated areas with water and allow to dry.
PRE-PRIMER COAT: Apply Potassium Silicate Concentrate diluted 100% with
water (1:1), or 10 liters to one (1) 10 liter bucket, on all damaged surfaces and allow
to dry for at least 12 – 24 hours; or apply one (1) coat of EcoForte Consolidator
diluted 100% with water, or 10 liters to one (1) 10 liter bucket, and allow to dry for
at least 8 – 12 hours. This applicaon applies only to unpainted, or mineral painted
surfaces only.

Aged Cement Stuccos
INTERIOR / EXTERIOR: Dirty and/or contaminated surfaces should be treated as
a priority prior to any intervenons of replacing or repairing stucco. All surfaces
should be cleaned and any aached algae removed manually or by mechanical
means, i.e., with a high-pressure washer. Stucco damaged by algae or mold should
be treated with EcoDis aer pressure washing. These instrucons are based on
unpainted portland based type cement stuccos.
PRE-PRIMER COAT : When new stucco repairs are performed on older, unpainted
cement stuccos, complete all removal of damaged stucco, rinse surfaces of dust,
and apply EcoForte Consolidator to older surfaces prior to applying new cement
stucco or make repairs. Pre-prime exisng surfaces applying one (1) coat of
EcoForte Consolidator diluted 100% with water, or 10 liters to one (1) 10 liter
bucket, and allow to dry for at least 8 – 12 hours.
